摘要

本文针对SiC牵引逆变器在全转速范围内良好的运行性能，将异步PWM控制与追求电流谐波最小的最优同步PWM控制相结合，研究了一种适用于SiC牵引逆变器的PWM控制策略。通过实验测试，对所提出的策略与常规策略在电机电流质量、电机损耗降低、电机温升和运行噪声抑制等方面进行了对比研究。本文给出了相关的实验结果，验证了所提出的PWM控制策略的有效性。

Experimental Study of the PWM Control Strategy For SiC Traction Inverter of Metro Vehicles

this paper studies a PWM control strategy suitable for SiC traction inverter aiming at good running performance of traction motor in full speed range, which combines the asynchronous PWM control and the optimal synchronous PWM control pursuing current harmonic minimum. The comparative study between the proposed strategy and the conventional strategy is conducted by experimental tests in terms of motor current quality, motor loss reduction, motor temperature rise and running noise suppression. The related experimental results have been detailed in this paper, which also confirm the validation of the proposed PWM control strategy.
